作为ListView DataTemplate容器的按钮控件wrt拖放ListView元素

<ListView>
    <ListView.ItemTemplate>
        <DataTemplate>
            <Button Content="{Binding}" AllowDrop="True" DragEnter="Button_DragEnter" DragOver="Button_DragOver" Drop="Button_Drop" />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

private void Button_DragEnter(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.StringFormat))
    {
        e.Effects = DragDropEffects.Copy;
    }
    else
    {
        e.Effects = DragDropEffects.None;
    }
}

private void Button_DragOver(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.StringFormat))
    {
        e.Effects = DragDropEffects.Copy;
    }
    else
    {
        e.Effects = DragDropEffects.None;
    }
}

private void Button_Drop(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.StringFormat))
    {
        string draggedItem = (string)e.Data.GetData(DataFormats.StringFormat);
        // 处理拖放操作，例如将拖放的元素添加到ListView中
    }
}
